Beware to those who take pride in the accuracy of their mock draft boards: Things might not be as they appear.

An NFL executive told CBSSports.com in a Tuesday report that "half of the teams in the top 10 are trying to trade out."

An intriguing statement, so let's try to break it down: The Indianapolis Colts are obviously staying put at No. 1, and the Washington Redskins would make America fear for their mental health if they traded out of the No. 2 slot only one month after mortgaging their future to get there.

"If we want to get out of that pick, we'll (determine) what it will take to get out of that pick," Spielman said. "Plus you have to be careful of how far you would want to go back (down in the draft). You have to know what you're looking at, depending on how far you go back. Are you getting yourself out of the (range of) the supposedly blue-chip type of players?"

If the Vikings stay put, it's believed they'll take USC All-American Matt Kalil, who's considered the only sure thing in the draft at offensive tackle. If a quarterback-hungry team wants to snatch Texas A&M's Ryan Tannehill before the Cleveland Browns pick at No. 4, Minnesota could have some nice leverage.
